Now I know this is probably going to offend other forum users but Jeeps are not very reliable. I fix a lot of modern makes but the jeeps always surprise me on the way they develop regular and expensive problems.
My Daughters WG which was purchased at 177,000kms has had the following litany of failures and it is now only just going through 300,000kms.
1) Clockspring failure,
2) Headlights crazed over needing polishing and ultimately replacement.
3 Front drivers door electric window motor failure,
4) The front passenger door electric window motor failure,
5) Front handbrake cable failure, then later the handbrake warning light switch on the lever breaking, causing no telltale warning of the handbrake being left on.
6) Factory CD player failing,
7) Wire breaking in drivers door loom sending the Body computer into a spin,
Wireless door locking and alarm arming stops working.
9)After being fixed another wire broke in the drivers door loom again sending the body computer into melt down.
10) Crank shaft sensor random failure, with no codes,
11) One coil in the coil pack failure, requiring full replacement.
12) Camshaft sensor drive bearing failure,
13) TPS require cleaning to stop random stalling,
14) Engine electric fan control module failing causing the fan to stay on and the battery to run flat.
15) Cabin fan speed resistor block failed, on high fan speed.
16) Water pump gasket started leaking had to be replaced, then the thermostat housing started leaking.
17) On a 38 degree day the body management computer locked up shutting of the Aircond and stopping the now fixed front electric windows from opening, turning the vehicle into a mobile sauna.

Auto trans output sensor failure multiple times put trans in limp home, eventually fixed by re-wiring the connector.
19) Power steering box jamming preventing full lock in one direction.
20) Rear shocker failure.
21) Rear sway bar link bushing failure.
22) Supposedly no-maintenance required life long fuel filter blocked up at around 190,000kms.
23) Oh and the O2 sensor drifting in calibration causing higher than necessary fuel consumption, which was replaced.
These are the ones I can think of at the moment, there has been more issues but at the moment I cannot recall them.
Now if I didn't fix it for her it would have been junked or traded years ago.
I have 3 parts WG grandies in my yard 2 with broken 4.7L v8's and one has 135,000kms in total the other 154,000kms in total, hardly a advert for reliable robust engines.
By comparison my wife drives a 9 year old KIA Optima she purchased new and it does 35,000kms commuting every year the car is now at 300,000kms and it has only required regular log bock servicing and a new passenger sun-visor which was replaced under warranty, no other attention required, nothing else, nada, nicht.
Never once let her down and only had 3 sets of tyres including the original set and one battery in that time.
